Clamp holder for fixing connecting rods and/or slide rails with sliding elements guided thereon

ABSTRACT

The clamping holder engages around the slide rail or rod with a slide rail receptacle by more than half of the circumference in a frictional engagement. A hollow-cylindrical continuation of the slide rail receptacle engages over an adjusting bearing and a fastening member on the outside. The hollow-cylindrical continuation is secured to the adjusting bearing so as to be fixed with respect to displacement axially and is secured to a cup-like fastening bushing of the fastening member so as to be fixed with respect to rotation.

The invention is directed to a clamping holder for fastening connectionrods and/or slide rails with sliding elements guided thereon accordingto the preamble of claim 1.

The brochure “Ordering and Construction Handbook, DORMA Manet, The GlassDesign System”, printed June 1998, page 3/04, discloses “individualparts and mounting of a slide rail for wall fastening and glassfastening” in which unwanted, costly bore holes are required in theslide rail. Further, page 3/05 of the above-cited brochure shows sliderail clamping holders which are constructed from two parts with aplastic plate disposed therebetween, so that they can be placed on theslide rail with sufficient pressing force. The plastic insert describedabove is not desirable because of its wear behavior under continuousload. Further, the multiple-part construction, particularly of sliderail clamping holders over which rolling cars of a sliding door systemrun, leads to a more expensive production of the slide rail clampingholders mentioned above and requires a high precision, particularly inthe area of the slide rail receptacle of the slide rail clamping holderso that the slide rail is supported without play in the slide railreceptacle of the slide rail clamping holder. Different distances from asubstrate construction, particularly a wall, which vary over the lengthof a slide rail, a carrying bar or holding bar can not be compensated bythe known devices.

Patent Application 101 19 908.2 describes a clamping holder which issupported by an end face of a hollow-cylindrical continuation of theslide rail receptacle directly at an end face of an adjusting bearing.The hollow-cylindrical continuation is fixed to the adjusting bearing bymeans of a fitting which is supported at the continuation so as to berotatable and fixed with respect to axial displacement on the one handand which is screwed to a cup-shaped fastening bushing on the otherhand. The slide rail receptacle is prevented from rotating only by thepressing pressure of the hollow-cylindrical continuation against theadjusting bearing and this is not always sufficient in all cases ofapplication because it can be detached easily.

It is the object of the invention to suggest a solution which makes itpossible to fasten the slide rail receptacle to the fastening member soas to be fixed with respect to rotation while ensuring the advantagesmentioned in the principal application in addition, wherein there is noneed for an additional fitting.

The invention meets this object with the teaching according to claim 1.

As before, an adjustment of the adjusting bearing relative to thefastening member and, therefore, an adjustment of all adjacent adjustingbearings relative to one another is made possible in that thehollow-cylindrical continuation of the slide rail receptacle engagesover the cup-like fastening bushing and the adjusting bearing, while onthe other hand an advantageous fastening of the slide rail receptacle tothe adjusting bearing and to the fastening member is also made possiblein this way. In this way, it is possible for the slide rail receptacleto be secured to the adjusting bearing so as to be fixed with respect toaxial displacement and to the cup-like fastening bushing of thefastening member so as to be fixed with respect to rotation in a simplemanner.

Other features of the invention are characterized by the subclaims.

At least one circumferentially extending groove is arranged in the outerwall of the adjusting bearing and a knurling or serration extending inaxial direction of the fastening bushing is arranged at the outer wallof the cup-like fastening bushing for fixing the slide rail receptacleto the adjusting bearing or to the fastening member.

In a further development of the invention, at least two threaded boreholes for receiving stud screws engaging through the wall are arrangedfor this purpose at a distance from one another in axial direction ofthe hollow-cylindrical continuation in the wall of thehollow-cylindrical continuation of the slide rail receptacle, whereinone of the spaced apart stud screws can be screwed into the groovearranged in the outer wall of the adjusting bearing and the other studscrew can be screwed into the area of the knurling or serration of thefastening bushing. Of course, a plurality of threaded bore holes inwhich corresponding stud screws securing the slide rail receptacle tothe adjusting bearing and fastening member can be screwed can be appliedover the longitudinal extension of the hollow-cylindrical continuationof the slide rail receptacle as well as over the circumference of thesame. The rail clamping section of the slide rail receptacle can beconstructed differently; the slide rail or the carrying bar or holdingbar can be grasped by a little more than half of the circumference orcompletely. The slide rail or the carrying bar or holding bar can besecured additionally relative to the rail clamping section in that therail clamping section has a threaded bore hole for receiving a studscrew.

Referring to the invention described above, by “slide rail” is meant arail or a bar at which sliding elements of different types ofconstruction, e.g., rollers, can be guided. However, the clampingholders described above can also be used in rails whose only function isto carry, e.g., curtains or the like. Further, the clamping holders aresuitable for fastening, e.g., handle elements which were definedgenerically as holding rods.

The invention will be described more fully in the following withreference to an embodiment example.

FIG. 1 shows a vertical section through a clamping holder;

FIG. 2 shows the section according to FIG. 1 with changed distance ofthe adjusting bearing;

FIG. 3 shows an enlarged view of an adjusting bearing;

FIG. 4 shows an enlarged view of the fastening member.

A clamping holder according to FIGS. 1 and 2 substantially comprises aslide rail receptacle 2 which forms an actual rail clamping section 3. Ahollow-cylindrical continuation 4 proceeds from the slide railreceptacle 2 and engages on the outside over an adjusting bearing 5 anda cup-like fastening bushing 8 of a fastening member 6. The fasteningmember 6 has a cup base 9 which is clamped against the substrateconstruction, not shown, by means of a fastening screw 5.

It can be seen from FIG. 3 that an adjusting bearing 7 has an externalthread 10 in the area of its outer wall 12, which external thread 10(see FIG. 4) can be screwed into an internal thread 11 of the cup-likefastening bushing 8 of the fastening member 6. The adjacent adjustingbearings 7 can be aligned so as to be flush with one another by screwingthe adjacent adjusting bearings 7 different distances into the fasteningmember 6. Further, it can be seen from FIG. 4 that a knurling 15 orserration extending in axial direction of the fastening member 6 isprovided in the area of an outer wall 14 of the cup-like fasteningbushing 8. The hollow-cylindrical continuation 4 of the slide railreceptacle 2 likewise engages over this knurling 15.

Insofar as the individual adjusting bearings 7 were aligned so as to beflush with one another before the slide rail receptacle 2 was placed onthe adjusting bearing 7 or on the fastening member 6, a groove 13arranged in the wall of the adjusting bearing 7 is likewise aligned. Aplurality of stud screws 19 which engage through a wall 16 of thehollow-cylindrical continuation 4 and which can be screwed into threadedbore holes 17 can be inserted into this groove 13 viewed along thecircumference of the hollow-cylindrical continuation 4 of the slide railreceptacle 2. In this way, the slide rail receptacle 2 is securedaxially relative to the adjusting bearing 7 and accordingly relative tothe fastening member 6. Other suitable stopping means can also be usedinstead of the groove 13.

Additional stud screws 19 which penetrate threaded bore holes 18 and canbe adjusted toward the cup-like fastening bushing 8 in the area of theknurling 15 secure the slide rail receptacle 2 with respect to rotationrelative to the fastening member 6.

The slide rail, not shown, can be secured relative to the rail clampingsection 3 by means of another stud screw, not shown, which projectsthrough a bore hole 20 in the rail clamping section 3.
